Be it known that Josnrn Pos'mnnocx,

States, and resident of Walpole in the county of Norfolk and State of Massachusetts, have invented an Improvement in Clamp-Buckles, of which the following description, in connection with the accompanying'drawings, is a speclfication, like letters on the drawings .IOPPG'. senting like parts. a present invention relates to clamp v specification of Lenora Patent. Patented Julyf19, .1921. Application ma I ebruary is, m1. mm in. 448,482.

"ley', I have devised the subject matter of the ends of a belt together when such belt is subjected to tenslon, and traveling over pulleys.

buckles, belt connectors, and the like, andmore particularly to a device of this character capable of connecting the ends of a belt, or analogous structure, passing over pulleys.

In the'manufacture of brake lining, it is the practice to make the same in various lengths and to then pass these lengths of lining through a treating bath in the further process of manufacturing. The length, of'linin is run over pulleys, the treatlng bath being located intermediate such pulleys, and due primarily to the; relatively greatlength of the lining, the said lining is subjected to considerable tension by the ulleys, so much so that heretofore it has been necessary to overlap the ends of the brake lining about four inches and rivet the ends together. As these riveted ends cannot be made usable when thus .riveted together, they are waste and must be cut oil the finished product. As these ends repre sent considerable outlay of money, it is desirable that means be devised for saving them, and as the only possible way of doing this is to eliminate the necessity for overlapping, various devices have' been proposed for temporarily holding the ends together without overlapping and without rivets. Such devices have included various forms of commercial belt clasps and buckles, all of which have failed. The

this class of devices, as above pointed out,

and to devise a connecting device that will the belt or brake lining against tension and at the same time make it possible for the clasp or buckle to pass readily over a pul-.

Another object is an improved device of the character which'will allow the same to pass readily over and around a pulley without lettmg go the ends of the belt or lining.

Other ob ects and novel features of construction and arrangements of parts will appear as the description of the invention progresses. In the accompanying drawing illustratmg the preferred embodiment of my invention,

Figure 1 is a top plan view,

Fig. 2 is a central longitudinal section of the same,

Fig. 3 is a bottom plan view, and

Fig. 4 is a sectional view on the line 4-.-4 of F 1g. 1 looking in the direction of. the arrows.

Referring to the drawing, 10 and 11 designate bars having their ends 12, 13 and 14:, 15 respectively, bent up at right angles, to form substantially U-shaped members, said ends being cut away to form cooperating hinge members 16 and 17. Slidably mounted .on the ends 12, 1 3 and 14:, 15 are members composed of a plate 18, provided with teeth 19, extensions 20 at the ends of said plate 18 being folded about the ends 12, 13

and 14, 15, as clearly shown in the drawings.

The teeth 19 lie in a plane m'akin an angle with the plate 18, the teeth belng long enough to engage with the bars 10 and 11, as clear Y shown in Fig. 2. A bar 21, separated from and lying parallel to the plate 18, at the side remote from the teeth 19, is connected to said plate in. any suitable manner, while an angular plate 22, also separated from and lying parallel to the plate, 18, adjacent the teeth 19, is connected to the plate 18 in any suitable manner.

To operate my improved device, the end ofthe brake lining or belt 23 is passed up through-or between the angular plate 22 and the bar'10"-or 11, then downward beperform the function of holding the ends of {tweenthe bar 10or 11- and the teeth 19,

then upward between the plate 18 and bar 21. Tli'e' plate 18 is now forced toward the bar' 10 cm 11, when the teeth 19 1 will serves to cause a tighter operation;

11- assisting in t s ippin gr lt 23 only Any tension of the liningor grip to. be taken thereon, and the hin s 16 and 17 allow the clamp buckle to artlculate, making itpos-- sible to have the lining or belt flex around the pulley without altering the lineof pull of the belt with respect to-the gripping members to. such an extent as to cause a loosening of the belt in the clamp.

While I have described the preferred embodiment of my invention somewhatin detail, it is to be understood that I may vary the size, shape and arrangement 0 parts constituting my device within wide limits without de arting from the spirit of the invention. y clam is stron very economically made, :11 wear a re atively long time, can be quickly diseng and does not injure the ends of the abric or linin No waste part is lost or removed. y clamp buckle being open does not prevent any part of the belt ends from being treated and therefore these end portions are usable. The clamping and buckle portions are so of the belt around a pulley does" not dielodge, loosen or disengage the clamping parts, but maintains the tightening 'p secured b my device. The clamp buc e can be re 'ly sta iped out of stock material and therefore can be manufactured eco-' nomioally, while maintaining its strength and SBI'VIOGtLbilitY. y

My invention is vfurther defined in'the form of claim as follows:

A clamp buckle comprising a pair of substantially U-shaped members hinged together to form a substantially rect lar artlculated frame, a toothed plate sli mounted on said members and having the teeth adapted to engage'wlth the cross bars of dsa1d lll-sha members, an lar gul i p ate or each toothed late i parallifi to said teeth and on y Hg side of the said cross bars; and a bar arallel to each of said guidin plates an on the opposite side of sald In testimony whereof I have name to this specification.
